Moreover, the invention relates to processes and intermediates for preparing these compounds, to the compositions comprising them and to their use for controlling phytopathogenic harmful fungi.

4-Aminopyrimidines having fungicidal action are known from EP-A 407 899 and BE-A 864,399. DE-A 3937284 describes fungicidal 2-pyridyl-4-benzylpyrimidines. WO-A 01/96314 discloses fungicidal pyrimidines which carry a cyanoamino substituent in the 2-position.

However, in many cases their activity is unsatisfactory.

It is an object of the present invention to provide compounds having improved activity.

We have found that this object is achieved by the pyrimidines of the formula I defined at the outset. Moreover, we have found processes and intermediates for their preparation and compositions for controlling harmful fungi, which compositions comprise these compounds.

The compounds I can be obtained by various routes.

The starting materials used can, for example, be the dichloropyrimidines of the formula V whose preparation is described in detail in WO-A O_(2/074753). In general, the substituent R¹ is initially introduced into the 4-position on the pyrimidine ring by coupling with organometallic reagents (see Scheme 1), giving the compounds of the formula VI.

In one embodiment of this process, the reaction is carried out with transition metal catalysis, such as Ni or Pd catalysis. Analogously, the radical R² can be introduced in the 6-position on the pyrimidine ring. In some cases, it may be advisable to change the order and to introduce the substituent R² first.

In the formulae (R¹)_(y-w)X_(w)-M^(y) and (R²)_(y-w)X_(w)-M^(y), M is a metal ion having the valency Y, such as, for example, B, Zn, Mg, Cu or Sn, X is chlorine, bromine, iodine or hydroxy, R¹ and R² are in particular C₁-C₆-alkyl and w is a number from 0 to 3. This reaction can be carried out, for example, analogously to the following methods: J. Chem. Soc., Perkin Trans. 1 (1994), 1187; ibid. 1 (1996), 2345; WO-A 99/41255; Aust. J. Chem. 43 (1990), 733; J. Org. Chem. 43 (1978), 358; J. Chem. Soc., Chem. Commun. (1979), 866; Tetrahedron Lett. 34 (1993) 8267; ibid. 33 (1992), 413.

What was said above refers in particular to the preparation of compounds in which R² is an alkyl group. If R² is a cyano group or an alkoxy substituent, the radical R² can be introduced by reaction with alkali metal cyanides or alkali metal alkoxides.

Sulfones of the formula IIIb are obtained by oxidizing the corresponding thio compounds IIIa. They are prepared under the conditions disclosed in WO 02/88127. Peracids of organic carboxylic acids or hydrogen peroxide, in particular, have been found to be suitable oxidizing agents. However, the oxidation can also be carried out using, for example, selenium dioxide.

Scheme 2 shows a similar synthesis route as Scheme 1, the only difference being that some synthesis sequences have been changed around. The route shown in Scheme 1 is particularly interesting for preparing the compounds 1′, in which R² is chlorine and for compounds I in which R² is a cyano or alkoxy group.

A further advantageous route for preparing the compounds I is shown in Scheme 3. Here, the substituent R^(2′) is a radical attached via carbon, such as alkyl, but not cyano. The pyrimidine ring is constructed by the routes described in WO 97/49697, DD 151404 and JOC 17 (1952), 1320.

The bromination is preferably carried out using elemental bromine or N-bromosuccinimide. This step can advantageously be carried out in an inert solvent, such as chlorobenzene, nitrobenzene, methylene chloride, chloroform, carbon tetrachloride or a carboxylic acid, such as acetic acid.

Suitable chlorinating agents for converting the hydroxyl compounds IX into the compounds X are, for example, POCl₃, PCl₃/Cl₂ or PCl₅, or mixtures of these reagents. The reaction can be carried out in excess chlorinating agent (POCl₃) or in an inert solvent, such as, for example, acetonitrile, toluene, chlorobenzene or 1,2-dichloroethane. The reaction is preferably carried out in POCl₃.

This conversion is usually carried out at 10 and 180° C. For practical reasons, the reaction temperature usually corresponds to the boiling point of the chlorinating agent used (POCl₃) or of the solvent. The process is advantageously carried out with addition of N,N-dimethylformamide in catalytic or substoichiometric amounts or of nitrogen bases, such as, for example, N,N-dimethylaniline.

In the case of nucleophilic heterocycles, R³ and the pyrimidine ring are preferably linked under the conditions of nucleophilic substitution, usually at 0-200° C., preferably at 10-150° C., in the presence of a dipolar aprotic solvent, such as N,N-dimethyl-formamide, tetrahydrofuran or acetonitrile [cf. DE-A 39 01 084; Chimia 50 (1996), 525-530; Khim. Geterotsikl. Soedin 12 (1998), 1696-1697].

In general, the components are employed in an approximately stoichiometric ratio. However, it may be advantageous to use an excess of the nitrogen heterocycle of the formula R³—H.

In general, the reaction is carried out in the presence of a base, which can be employed in equimolar amounts or else in excess. Suitable bases are alkali metal carbonates and bicarbonates, for example Na₂CO₃ and NaHCO₃, nitrogen bases, such as triethylamine, tributylamine and pyridine, alkali metal alkoxides, such as sodium ethoxide or potassium tert-butoxide, alkali metal amides, such as NaNH₂, or else alkali metal hydrides, such as LiH or NaH.

Moreover, the pyrimidine ring can be linked with the phenyl ring under the reaction conditions of the Suzuki coupling (JOC 67 (2002), 3643; Angew. Chem. 114 (2002), 4350 and literature cited therein).

When constructing the pyrimidine ring, it may be advantageous to introduce the heterocyclyl substituent R³ together with the amidine component, as shown in Scheme 4a. In this case, R^(2′) is again a radical attached via carbon, such as alkyl (but not cyano).

In turn, pyrimidines I, in which R² is halogen or an alkoxy group can advantageously be prepared by the route shown in Scheme 4b. Starting with keto esters XIIb and amidines, the compounds XIII are obtained, which, depending on the nature of the substituent R², can be converted into the respective target compounds 1 or 1′.

As already mentioned a number of times above, for preparing the pyrimidines I in which R² is a radical attached via carbon, such as alkyl (but not cyano), it is advantageous to use 1,3-dicarbonyl compounds (XIIa) as starting materials. Reaction with urea gives, as shown in Scheme 5, the compounds XIV, which can be chlorinated to give XV.

In the case of nucleophilic heterocycles, the substituent R³ is introduced under conditions of nucleophilic substitution.

Moreover, the formation of the bond can also be carried out with transition metal catalysis, such as, for example, under the reaction conditions of the Suzuki coupling.

Furthermore, Scheme 6 shows how the chain of the substituent R¹ can be extended.

The reaction mixtures are worked up in a customary manner, for example by mixing with water, separating the phases and, if appropriate, chromatographic purification of the crude products. Some of the intermediates and end products are obtained in the form of colorless or slightly brownish viscous oils which can be purified or freed of volatile components under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, purification can also be carried out by recrystallization or digestion.

If individual compounds I are not obtainable by the routes described above, they can be prepared by derivatization of other compounds I.

However, if the synthesis yields isomer mixtures, a separation is generally not necessarily required since in some cases the individual isomers can be converted into one another during the preparation for use or upon use (for example under the action of light, acids or bases). Similar conversions may also occur after use, for example in the treatment of plants in the treated plant or in the harmful fungus to be controlled.

The compounds I are employed by treating the fungi or the plants, seeds, materials or soil to be protected from fungal attack with a fungicidally effective amount of the active compounds. The application can be carried out both before and after the infection of the materials, plants or seeds by the fungi.

The fungicidal compositions generally comprise between 0.1 and 95%, preferably between 0.5 and 90%, by weight of active compound.

When employed in plant protection, the amounts applied are, depending on the kind of effect desired, between 0.01 and 2.0 kg of active compound per ha.

In seed treatment, amounts of active compound of 0.001 to 0.1 g, preferably 0.01 to 0.05 g, per kilogram of seed are generally necessary.

When used in the protection of materials or stored products, the amount of active compound applied depends on the kind of application area and on the effect desired. Amounts customarily applied in the protection of materials are, for example, 0.001 g to 2 kg, preferably 0.005 g to 1 kg, of active compound per cubic meter of treated material.

The compounds I can be converted to the usual formulations, e.g. solutions, emulsions, suspensions, dusts, powders, pastes and granules. The application form depends on the respective use intended; it should in any case guarantee a fine and uniform distribution of the compound according to the invention.

The formulations are prepared in a known manner, for example by extending the active compound with solvents and/or carriers, if desired using emulsifiers and dispersants. Solvents/auxiliaries suitable for this purpose are essentially:

-   -   water, aromatic solvents (for example Solvesso products,         xylene), paraffins (for example mineral oil fractions), alcohols         (for example methanol, butanol, pentanol, benzyl alcohol),         ketones (for example cyclohexanone, gamma-butyrolactone),         pyrrolidones (NMP, NOP), acetates (glycol diacetate), glycols,         fatty acid dimethylamides, fatty acids and fatty acid esters.

I) Granules (GR, FG, GG, MG)

0.5 part by weight of the active compounds is ground finely and associated with 95.5% carriers. Current methods are extrusion, spray-drying or the fluidized bed. This gives granules to be applied undiluted.

J) ULV Solutions (UL)

10 parts by weight of the active compounds are dissolved in an organic solvent, for example xylene. This gives a product to be applied undiluted.

The active compounds can be used as such, in the form of their formulations- or of the application forms prepared therefrom, e.g. in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, compositions for broadcasting or granules, by spraying, atomizing, dusting, broadcasting or watering. The application forms depend entirely on the intended uses; they should in any case guarantee the finest possible dispersion of the active compounds according to the invention.

Aqueous application forms can be prepared from emulsion concentrates, pastes or wettable powders (spray powders, oil dispersions) by addition of water. To prepare emulsions, pastes or oil dispersions, the substances can be homogenized in water, as such or dissolved in an oil or solvent, by means of wetting agents, tackifiers, dispersants or emulsifiers. However, concentrates comprising active substance, wetting agent, tackifier, dispersant or emulsifier and possibly solvent or oil can also be prepared, which concentrates are suitable for dilution with water.

The concentrations of active compound in the ready-for-use preparations can be varied within relatively wide ranges. In general, they are between 0.0001 and 10%, preferably between 0.01 and 1%.

The active compounds can also be used with great success in the ultra low volume (ULV) process, it being possible to apply formulations with more than 95% by weight of active compound or even the active compound without additives.

Oils of various types, wetting agents, adjuvants, herbicides, fungicides, other pesticides and bactericides can be added to the active compounds, if need be also not until immediately before use (tank mix). These agents can be added to the compositions according to the invention in a weight ratio of 1:10 to 10:1.

The compositions according to the invention can, in the application form as fungicides, also be present together with other active compounds, e.g. with herbicides, insecticides, growth regulators, fungicides or also with fertilizers. On mixing the compounds I or the compositions comprising them in the application form as fungicides with other fungicides, in many cases an expansion of the fungicidal spectrum of activity is obtained.

The fungicidal action of the compounds of the formula I was demonstrated by the following experiments:

The active compounds were formulated, separately or jointly, as a 10% emulsion in a mixture of 70% by weight of cyclohexanone, 20% by weight of Nekanil® LN (Lutensol® AP6, wetting agent having emulsifying and dispersant action based on ethoxylated alkylphenols) and 10% by weight of Wettol® EM (nonionic emulsifier based on ethoxylated castor oil) and diluted with water to give the desired concentration.

Use Example 1: Activity Against Early Blight of Tomato Caused by Altemaria solani

Leaves of potted plants of the tomato cultivar “Large Fruited St. Pierre” were sprayed to runoff point with an aqueous suspension having the concentration of active compounds stated below. The suspension or emulsion was prepared from a stock solution comprising 10% of active compound in a mixture consisting of 85% of cyclohexanone and 5% of emulsifier. The next day, the leaves were infected with an aqueous spore suspension of Alternaria solani in a 2% biomalt solution having a density of 0.17×10⁶ spores/ml. The plants were then placed in a water-vapor-saturated chamber at 20-22° C. After 5 days, the blight on the untreated but infected control plants had developed to such an extent that the infection could be determined visually in %.

In this experiment, plants which had been treated with 250 ppm of active compound I-01, I-02 or I-04 showed an infection of 0 to 5%, whereas the untreated plants were 100% infected.

Use Example 2: Activity Against Gray Mold on Bell Pepper Leaves Caused by Botrytis cinerea

Bell pepper seedlings of the cultivar “Neusiedler Ideal Elite” were, after they had 4-5 well-developed leaves, sprayed to runoff point with an aqueous suspension of the concentration of active compounds stated below. The suspension or emulsion was prepared from a stock solution comprising 10% of active compound in a mixture consisting of 85% of cyclohexanone and 5% of emulsifier. The next day, the treated plants were inoculated with a spore suspension of Botrytis cinerea which contained 1.7×10⁶ spores/ml in a 2% aqueous biomalt solution. The test plants were then placed in a climatized chamber at 22-24° C. and high atmospheric humidity. After 5 days, the extent of the fungal infection on the leaves could be determined visually in %.

In this experiment, plants which had been treated with 250 ppm of active compound I-01, I-02 or I-04 showed an infection of 0 to 5%, whereas the untreated plants were 100% infected.
